The Charging unit made by Enel X called a JuiceBox 40 failed to complete a charge. Upon examination of the charger it was determined that the plug from the unit to the 240V receptacle was fused to the outlet and could not be removed. When my electrician opened the box he was able to force the plug out of the outlet. He found that the plug was burned as well as the copper wire that went to the plug from the electrical box.

I started directing the car to the side of the road to park. As I was guiding the car to a stop, with my foot on the brake, I was about 12 ft. from the car in front of me when the car suddenly accelerated. The vehicle accelerated for approximately 10 ft. before the anti-collision system auto-braked the car just prior to impacting the car in front of me.

The vehicle began making a clicking/ticking sound under acceleration and deceleration. The noise progressively worsened until The dealer diagnosed the motor as failing internally and replaced it under warranty. Several people online in forums have experienced the same issue, some cases resulted in the reduction gear catastrophically failing causing the vehicle to suddenly stop accelerating. I worry that this issue may result in more sudden drivetrain failures because of how widespread the problem is. Hyundai does not seem to have a definite solution as the noise comes back for many owners.
